Description

Technical field: [0001] The invention relates to a radio frequency power synthesizer in the field of microwave communication, in particular to a microwave low-band ultra-miniature power synthesizer with high gain, high integration and high efficiency. Background technique: [0002] In the field of microwave communication, base station transmitters and small complete machines have high requirements on output power, requiring the signal to have sufficient power when transmitting, so that the signal can be transmitted far enough to cover a certain area. However, it is often difficult to obtain such a high power by single-channel power amplification. At this time, it is necessary to use power combining technology. Power combining is to combine smaller power into larger output power. At present, in order to obtain a large enough gain in the RF power combiner, multi-stage amplification is usually used, and some require an external bridge, which makes the product bulky, complex in ...
